Application tiled February15, 1915. Serial No. 8,280.

To all whom it may concern! Be it known that we, CLARENCE Irl. How* Anoand HARRY M. PFLAGER, citizens'oi the UnitedStates, residing at St.Louis, Mis# souri, have invented a certain new and useful Improvement inCar-Trucks, ofA whichthe following is a full, clear, and exact de-.scription, such as will enable others skilled`r verse section taken onthe line 2-'-2 ci Fig.v

l. Fig. 3 is a perspective view of the end portionof the spring plankthat is used in our improved truck. I

Our invention relates generally to car trucks and more particularly tothe means utilized for holding the elliptic springs `in proper` positionupon and between the spring plank and cross bolster.

The principal object of our invention is to provide ineans, preferablyin the form of lugs or flanges, on the spring plank and press bolsterfor the purpose of holding the spring sections against transverse move*ment relative to said spring plank and cross bolster.

Further objects of our invention are to eliminate the spring seatsordinarily used upon cross holsters and spring planks, thus providingmore space for the brake mechanism which is associated 'with the truckand likewise more space for the swing hangers which support the springplank.

With the foregoing and other objects in view, our invention consists incertain novel features of construction and arrangement of parts,hereinafter more fully described and claimed.

In the drawings, we have shown a porti on of a six wheel truck, theframe of which includes wheel pieces 10, end rail il and paralleltransoins 12 between which the usual cast metal cross bolster i3 ispositioned. Positioned in suitable bearings near the ends of thetrans-oms 12 are pins le from which depend the usual swing hangers 15which support the spring plank 16 the saine being formed in one piece,preferably by casting. Positioned upon the end portions ot the spring'plank 16 are the usual Patented July i3, llitilr i ellip'tcspringsections l? ythe `saine yield- 'i v.ingly supporting the crossbolster13.

In our improved construction the usual bands 18 which surround theleaves of each i spring section bear directly upon the spring plank andagainst the undersideof the Across bolster 13,- and in order to hold theAsprings against longitudinal movement, the spring plank has formedintegral with itA near each end a pair'of transversely disposed ribs orflanges 19, and thel .cross ybolster-13 `has formed integral with it onthe underside corresponding transversely disposed ribs or' iianges 20and when the parts are properly assembled lthe bands v18 engageIbetween-'the'v respective pairs of ribs.

ln order to hold the spring sections 17 inv proper position between thespring plank and cross bolster and prevent its transverse niovementrelative thereto, upwardly pro-vr gecting lugs 2l are formed integralwithk the spring plank, and corresponding downwardly projecting lugs 22are formed integral withthe cross bolster. These lugs project betweenthe spring sections, kthus holding the saine against lateral movement.l/Vhen two-section springs are used it is only necessary to provideasingle lug, the saine extending between the two sections and when morethan two sections are used, lugs are provided for each space between thesections. By providing lugs between the spring sections for holding thelatter in proper position, the usual' spring seats which are utilized inconnection with spring planks and cross bolsters are eliminated, and asa result, more space is provided to .the sides of the spring plank andcross It will be readily understood that minor changes in the size, formand construction of the various parts of our improved cari truck can beTriade and substituted 'for thos'a herein shown and described, withoutdes, partingfrom the spirit of our invention',v the scope of which isset forth. in the. ap` pended claims.

We claim:

1. ln a ear truck, a east metal spring plenk, elliptic springspositioned thereupon, lugs integral with and projecting upwardly fromthe spring plank for holding the springs lagainst longitudinal andtransverse movement, end a bolster supported by said springs.

In e eur truck, e east metal spring plank, pri-irsA of transverselydisposed ribs formed integml with the top of seid spring plank near itsends for engaging parts of the springs positioned on said spring plank,and lugs integral with and projecting upwardly from the spring plankadju.- eent te the inner members of said pairs of ribs.

ln a enr truck, e east metal bolster rovided on its underside withtransversely disposed pairs oi: ribs which are adapted to engage partsof the springs upon which the bolster is carried, and lugs formedintegral wwith the underside of seid bolster adjacent te the innermembers of the pairs of ribs, which lugs are adapted to engage betweenthe sections of the springs which support said bolster.

el. ln e eer truck, :i enst metal spring plank, pairs oi transverselydisposed ribs formed integral with the top of said spring plank neer itsends for engaging); parts of 'the sprinfs positioned on said spring'plank, und lugs integral with and projeetinf upwerdly from the springplank adjacent to the inner members of snid pairs el' ribs, which lugs:1re adapted to engage between the sections of the springs positioned onsaid springplank.

5. ln :t eer truck, :i east metal spring' plank provided in its topsurface neer its ends with transversely disposed pairs of shoulderswhich nre adapted to engage pei-ts or' the springs positioned on saidspring plzuik, and upwardly projecting lugs formed integral with saidspring plank ed jacent to the inner shoulders, which lugs ure adapted toengage between the sections et the springs supported by said springplank.

G. in it can; truck, :i oust metal bolster provided in its undersidewith pairs el trans versely disposed shoulders which are adepted toengage parts of the springs which support said bolster, und dependinglugs integri-ul with said bolster n mr the inner shoulders, which lugs:ire adapted to engage between the sections of the spring which supportthel bolster.

ln testimony whereof we hereunto aii'ix our signatures in the presenceof two witnesses, this 10th dry er leloruztry, 1915.
